The Olympic Delivery Authority will appoint three main contractors to undertake the management of landscaping for the 2012 Olympic Park—the North Park contract, the South Park contract and the Greenway contract. For off-park venues, the responsibility for landscaping will rest with the main contractor appointed to each venue. The ODA would then expect each main contractor to use subcontractors and suppliers to carry out the required works.
Until the main contractors have been appointed, I cannot say how many companies will be involved, as this will depend on how the works are then phased and split with each contractor.
To help businesses access 2012-related contracts, the London 2012 Business Network was launched in January of this year. A key part of this is CompeteFor, an online brokerage service matches the profiles of suppliers and buyers, enabling businesses to directly compete for contracts, including landscaping contracts. I would encourage companies in your constituency to take advantage of this opportunity.
